What this bill does
AI plain-language summaryThis bill changes the rules about whether states can set their own vehicle emission standards that are stricter than federal ones. It says that states can no longer get permission from the Environmental Protection Agency (EPA) to create rules that would directly or indirectly limit the sale or use of new cars and trucks powered by internal combustion engines (traditional gasoline or diesel engines). It also requires the EPA to take back any such permissions that were granted between January 1, 2022, and the date this bill becomes law. On top of that, the EPA would not be allowed to decide that any updated state standards fall under a permission that was already given.
